WINDOWI-SCREEN.

SPECIFICATION forming part of Letters Patent No. 329,287, dated October27, 1885.

Application filed July 15, 1885.

To all whom it may 651mm: 4

Be it known that I, WILLIAM M. DANA, of Ripon, county of Fond du Lac,State of Wisconsin, have invented a new and nseful'lrriprovement inVVindow-Screens, of which the following is afull, clear, and exactdescription, reference being had to the accompany,- ing drawings,makin gpart ofthis specification. My invention relates to an improvement inwindow-screens; and it consistsin the peculiar construction andcombination of devices that will be more fully set forth hereinafter,and particularly pointed out in the claims.

In the accompanying drawings, Figure 1 is an elevation of awindow-screen embodying my invention applied to a window. Fig. 2 is adetail transverse vsectional view taken on the line a: a: of Fig. 1.Fig. 3 is a detail vertical sectional view taken on the line z z ofFig.1.

A represents the frame of the screen,which consists of the side rails,a, the top rail, b, and the bottom rail,c. A wire-gauze,d,is stretchedacross the frame and secured at its edges'to the rails thereof, asshown. The side rails 'are rabbeted on their inner sides, as at e, and

in these recesses are fitted extension-strips B. The side strips, 13,can be moved in or out to fit the screen in the window-frame below theupper sash, thus enabling the lower sash to be raised or lowered withoutdisturbing the screen.

0 represents headed bolts that pass through openings from the innersidesof the side rails, a, and are provided with screw-threads on their outerends, which are screwed into the inner sides of the extension-strips B.Coiled springs D are placed on these bolts, and bear between theextension-strips and the side rails, so as to press the strips outagainst the inner sides of the frame, and thereby secure the screentightly therein. The inner ends of the springs D rest in openings f inthe outer sides of the side rails, so as to allow the strips B to bepressed inwardly, in order to raise the screen or remove it from thewindow-frame. Knobs E are secured to the strips, as shown,

by means of which the strips may be drawn inwardl-y when it is desiredto remove the screen from the window.

To the" upper side of the top rail, b, is secured a rubber. strip, f,that extends laterally beyond the inner side of the screen and bearsagainst the outer side of the bottom rail of the top sash when thescreen is in place in the window-frame, and thereby makes a tight SerialNo. 171,686. (No model.)

joint between the screen and the top sash, to

prevent insects from entering at that point. A U-shaped keeper, G, ispivoted tothQ top rail of the screen by an eye-screw, 9, through the eyeof which passes one arm of the keep er, the screw being embedded in thetop rail of the screen. This keeper can be swung outwardly from theinner side of the screen and placed under the lower rail of the uppersash, the arms of the keeper embracing opposite sides thereof, so as tosecure the screen firmly to the upper sash without marring or llljlllyto the latter. As the screen is secured in the frame below the top sash,the lower sash may be raised or lowered at will without the necessity ofremoving the screen. The extension-strips may also be applied to doors,to cause the latter to fit tightly in their frames when closed, and thusanswer the purposes of a weather-strip.

Awindow-screen constructed as hereinbefore described is light, cheap,and simple, is

with laterally-projecting rubber strips to bear against the \vindowsash,and this I disclaim.

Having thus described my invention l/ claim 1. The combination, withawindow-screen, of the U-shaped keeper G, pivoted to the screen at itsupper side, tgwre said screen to the lower side of the [Ml],

substantially as described.

2. A window-screen adapted to fitin awindow-frame below the upper sash,andhaving the laterally-extended rubber strip f at the upper side of thescreen to bear against the upper sash to form a tight joint therewith,and the U shaped keepers pivoted to the screen to embrace the lower sideof the upper sash pi Q and secure the screen thereto, substantially asdescribed.

In testimony whereof I have hereunto set my hand this 1st day of July,A. D. 1885.

WILLIAM M. DANA.
